Shallow Labor Pool Forces Industrial Technology Change

This article was written by engineering technician at E Tech Group- Bradly Wright and originally appeared in Automation World. Click here to view the original post. To maintain uptime, ensure compliance, and maximize the use of skilled labor, more facilities than ever are centralizing production control and monitoring. There’s a reason more and more facilities are changing the way their production floor has been operating for decades: the current labor shortage. When production floors were fully staffed, it wasn’t uncommon to find a worker stationed at each point in the manufacturing process, monitoring the HMI (human-machine interface) as the PLC (programmable logic controller) repeated its programmed task, ensuring consistency and efficiency at each step. PLCs were designed to function optimally by executing one line of code at a time—with nothing else running in the background. This was a completely viable solution when manpower was available to individually monitor each process. Even now, the PLC remains in wide use because of its flexibility and ease of programming. It’s still incredibly reliable, allowing the operator to make on-the-fly adjustments thanks to real-time information transmission. The big difference now is in how PLCs are being used as more manufacturers are forced to implement a control system that will help centralize production control and monitoring. The use of a distributed control system (DCS) allows a central point of monitoring and operation that coordinates and supervises an entire plant completing a variety of processes and can be scaled facility wide. A PLC, however, is isolated in its control and monitoring. Because the DCS allows full visibility and control into a plant’s production, it helps make it possible to run at full capacity with a limited staff. What does the future look like? If the current trend continues, the production and manufacturing industry will likely take … Continued

Utilizing the AVEVA PI System for a Large Pharmaceutical Client

The generation, maintenance and use of historical process data is always an important part of the discussion in the pharmaceutical manufacturing sector where transparency and traceability throughout the automation system is key. It affects things such as regulatory compliance, process optimization, business strategy, and overall viability in the marketplace. To enhance this aspect of their business, one of our clients chose to leverage the AVEVA PI Software Suite in their control system retrofit. The AVEVA PI system is one of the leaders in the industry and provides various architecture and licensing options to accommodate customers’ needs. The AVEVA PI is a product of industry collaboration and incorporates OSISoft’s data management prowess with AVEVA’s engineering expertise. Utilizing this powerful automation platform enhances process visibility, decision-making, and optimization throughout the industrial value chain. The functionality of the AVEVA PI system can be broken down into the following subsections: collecting data, storing data, contextualizing data, and visualizing/accessing data. Redundant Data Collection Collecting data is the process of taking data from a source and sending it along the pipeline to be stored. In this use case, the data sources are PLCs and relational databases. The PI System uses PI Interfaces and Connectors to perform the data collection. AVEVA offers over 450 interfaces, allowing for collection from a vast array of data sources. In the past, the client had issues with its legacy data collection; data gaps and outages would occur too frequently. PI Interfaces facilitate data collection and allow for redundancy to ensure that there is not a single point of failure in the system. In addition to the available redundancy, PI interfaces also provide buffering: if the archive itself is unavailable, the interface will store data locally until the archive is available again. The buffered data is then forwarded to the archive, … Continued

Building an Automation Infrastructure

E Tech Group Director of Operations, Cassy Gardner, is featured as a part of the following article, which originally appeared in Food Engineering Magazine. The better you know what you already have in place, the easier it is to plan for a successful future. Unless you operate a brand-new state-of-the-art plant, you probably have a facility with a mish-mash of aging processing and packaging equipment with various vintages of network and application software support—maybe several areas still requiring manual labor. As technology continues to move forward, piecemeal, aging automation systems reach a bottleneck, hampering further growth and competitiveness for the company. For older facilities, knowing where and what to automate—what your priorities should be—is important to helping you stay competitive now and in the future. For those with new plants, it’s never too late to plan your future goals – today’s turnkey automated factory is tomorrow’s control system retrofit. In this article, we consider how to know when, where and what to automate in an older facility. Of course, the answers to these questions won’t be the same for every plant, but we can see a framework essential to all automation projects come through regardless. Automation Solving Labor Shortage Problems The primary motivations driving food processors to automate their operations include labor reduction, increased production efficiency and enhanced product quality, says Ryan Beesley, CAP, Regional Engineering Manager at Kennewick, Concept Systems, Inc., a Control System Integrators Association (CSIA) Certified Member. But the labor aspect has especially been an acute problem for the last couple of years as manufacturers realize the labor shortage is not a short-term problem. Other Advantages of Process Automation Getting Started in the Planning Process No two automation solutions will be the same—each one is unique. “Custom automation solutions typically begin with a feasibility and concept phase … Continued

What are the Current Pain Points with Supporting Utilities Such as Ammonia Refrigeration and Steam Generation?

When you look at supporting industrial utility systems like ammonia refrigeration, you may wonder how often you might actually encounter them. They appear far more in your daily life than you realize. Look at the rooftop of an industrial facility and see if you notice orange pipes or windsocks. It is likely that this facility has an ammonia refrigeration system. Now, when it comes to the maintenance of these systems, there are a few pain points that tend to plague facilities more than others. Aging Systems: These systems are decades old in most cases, many around 20–30 years old, and tend to require human labor occasionally. By comparison, the average industrial boiler system in the United States is around 30-40 years old, and many of these systems require large amounts of human interaction more often. The thing both these systems share is a lower level of automation, utilizing control panels dependent on relays and contactors to implement control schemes. Incorrect Sequencing Causing Inefficiency: Not only primitive automation, but the inability to adapt to changes in demand or load can present a challenging issue. This can often result in incorrect sequencing equipment due to simple control implementations, leading to lower overall system efficiency. A common instance of incorrect sequencing is having the largest piece of equipment either always running or brought online when demand is lower, which can be less efficient in its operation and energy consumption. Keeping in mind these systems can also be slow to start or restart if personnel are not quickly notified when a fault or issue occurs. Lack of Integration into Larger Control Systems: Even if a modern system has been implemented, it is less likely that it is part of a BMS (Building Management System) or DCS (Distributed Control System) which could better control … Continued
